Playing techniques

Despite their apparent similarity, keyboard instruments of different types require different techniques. The piano hammer mechanism produces a louder note the faster the key is pressed while the harpsichord's plectrum mechanism does not perceptibly vary the volume of the note with different touch on the keyboard. The pipe organ's volume and timbre are controlled by the flow of air from the bellows and the stops preselected by the player. Players of these instruments therefore use different techniques to color the sound. An arranger keyboard may be preset to produce any of a range of voices as well as percussion and other accompaniments that respond to chords played by the left hand.

Even though the keyboard layout is simple and all notes are easily accessible, playing requires skill. A proficient player will have undertaken much training to play accurately and in tempo. Beginners seldom produce a passable rendition of even a simple piece due to lack of technique. The sequences of movements of the players hands can be very complicated. Problems include wide-spanned chords, which can be difficult for people with small hands; chords that require unusual hand positions that can initially be uncomfortable, and fast scales, trills and arpeggios.

Playing instruments with velocity sensitive (or, dynamic) keyboards (i.e., that respond to varying playing velocity) may require finger independence, so that some fingers play "harder" while others play more softly. Keyboardists speak of playing harder and softer, or with more or less force. This may accurately describe the player's experience—but in the mechanics of the keyboard, velocity controls musical dynamics. The faster the player depresses the key, the louder th
